MATTRESS.

SPECIFICATION forming part of Letters Patent No. 772,602, dated October 18, 1904.

Application filed March 14, 1904. Serial No. 198,163. (No model.)

To all whom it may concern.-

. Be it known that I, RAYMOND S. BARTLETT,

of Franklin, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Mattresses, of which the following is a specification.

This invention has relation to mattresses, and has for its object to provide certain improvementstherein in consequence of which the mattress is rendered 'more resilient and less likely tomat and become flattened than heretofore.

It has hitherto been proposed to employ as a mattress-stuffing cotton fiber and also wool fiber made from waste or refuse woolen goods, rags, -&c Mattresses made of cotton fiber in time become flattened and lose theirresiliency, whereas stuffing made of shoddy or woolen fiber from refuse woolen goods is more or less greasy and lacks that resiliency which is essential in a mattress. According to my invention, however, I employ a stuffing con sisting of what is termed knickerboeker 0r nubbed stock. This may be formed fromthe relatively coarse noil from a woolcombing machine, anditconsists of bunched or curledballs of wool fiber. While it is not essential that the stock may be formed of the noil from a wool-combing machine, since longer fibers of wool may be employed for the purpose, yet the noil may be preferably used on account of its relative cheapness. The fibers may be passed through a card with the workers or small carding-cylinders set off from the main cylinder, so that the stock is rolled into balls or nubs instead of being carded. A mass of this material possesses great resiliency, does not felt, and is not matted after a long period of use. v

On the drawings, Figure 1 represents a mattress with the' tick open to illustrate the stuffing. Fig. 2 represents a mass of knickerbocker, actual size, ing.

In the drawings the tick is indicated at a and the stufiing at b. The stuffing is shown in Fig. 2, and it will be seen that it consists of the small balls or nubs 0 0 of woolen fiber tightly coiled or bunched.

A mattress having a stuffing of knickerbocker is sanitary, .in that respect being unlike 'a mattress formed of shoddy with its consequent danger of containing germs of contagious' diseases. The stufiing, consisting of relatively tightly rolled balls or nubs of the fiber, contains a large quantity of air in its which is used as the stuffinterstices, so as to render it soft and cornfortable to the human body. A mattress stufl'ed with it never gets lumpy or has'to be made over; The longer it is subjected to use and the more the bunches or balls of the wool fiber are agitated the more tightly they rolland the more resilient the mattress becomes. r

' Having thus explained the nature of the inventionand described a way of constructing and using the same, although without attempting to set forth allof the forms in which it may RAYMOND S. BARTLETT.
